The piano key (PK) weir has advanced over the labyrinth weir to increase the discharge
capacity. Piano key weirs exhibit nonlinear flow behavior and are easy to place on the …

A method is presented for the hydraulic design and analysis of labyrinth weirs based upon
the experimental results of physical modeling. Discharge coefficient data for labyrinth weirs …

Dams are multipurpose structures that provide water for drinking purposes, hydroelectric
power generation, navigation, industrial uses, and irrigation, in addition to flood control. The …

Currently, many existing spillways located throughout the globe require rehabilitation due to
dam safety issues. Consequently, there is an increasing need for design tools that facilitate …

Labyrinth weirs present an effective solution for high discharge efficiency in space-restrictive
situations. However, these weirs exhibit negative effects (vibrations, noise, and instability) …

Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes
containing speculation, on a civil engineering topic of general interest and relevance to the …

Hydraulic engineering of dams and their appurtenant structures counts among the essential
tasks to successfully design safe water-retaining reservoirs for hydroelectric power …

Current hydraulic design/analysis literature for labyrinth weirs is limited to headwater ratio
(total upstream head/height of weir) values less than 1.0. This study utilized physical and …

Abstract Piano Key Weir (PKW) is an evolution with an efficient implementation over
conventional labyrinth weir, especially at low heads. It is used as the crest of spillways and …

Due to their small footprint and efficient hydraulic performance, piano key weirs (PKWs)
have been gaining growing attention in the past two decades. Besides the primary …
